Question

When I was trying to create a new react app using npx create-react-app example_app, I get this error

[Your cache folder contains root-owned

Answer 1

I also tried all of the above steps on my MAC Catalina, but didn't resolve my issue. These steps resolved my problem:

npm update
npx --ignore-existing create-react-app my-app

Thanks to this comment

Answer 2

Try sudo npx create-react-app example_app or in my case sudo npm install @vue/cli

I tried everything else here, but in the end realised that it might just be the command that I was running was not able to escalate the correct permissions.

Answer 3

It helped me: Remove and install npm again
